A new paper describes how scientists used the tool to identify an important role for TRIM24 in mediating telomere repair after cells divide.

Each time a cell divides, a small section of each chromosome's protective cap - the telomere - is worn away. Most cells use ...

New imaging tools reveal how within an hour of infection, the virus begins to alter our chromosomes to kick-start its own replication.

Flip open a high-school biology textbook, and the rule seems tidy: two X chromosomes mean girl, and an X paired with a Y means boy. That much smaller Y chromosome carries the SRY gene, which is the ...
